Coffee Power
Scientists have whirled coffee waste into electricity for the first time, in research that could assist farmers and curb pollution in the developing world. The coffee industry produces a huge amount of liquid waste during the procedure of turning the fresh material of the tree, the coffee cherries, into the 9.5m tons of coffee the world generates each year. While coffee waste has been utilized as biofuel before, and compacted to be sold as “biologs” to be burned, the project is supposed to be the first to generate electricity from such waste .
